ATTACHMENT TO ELBOWS OF WIND-STACKERS.

Application filed April 9, 1907. Serial No. 367,295.

To all 'whom it may concern:

Be it known that I, SIDNEY W.'ERIoKsoN, a citizen of the United States, residing at the city of Red Wing, in the county ofGoodhue and State of Minnesota, have invented a new and useful invention, an Attachment to Elbow of Wind-Stacker of a Threshinghlachine, of which the following is a specification.

My invention relates to the clearing out of straw that clogs in the windstacker of a threshing machine without stopping the machine as is now done, which will be explained herein. I attain this obj ect by the mechanism which will be illustrated in the accompanying drawings in which:

Figure 5 shows the elbow, a section, of the windstacker of a threshing machine without my attachment afiixed thereto. Fig. l is a side view of the elbow of a windstacker of a threshing machine with my invention affixed thereto and in position as when the machine is running and straw passing through the stacker tube. Fig. l also shows the elbow open to permit the cleaning of straw therefrom. Fig. 2 shows a cross section of a stacker tube A at e. Fig. 3 is a cross section of parts of the stacker tube B and O on lines a a and b b. Fig. 4 is a front elevation of the whole device with my attachment affixed to the elbow of the windstacker.

Similar letters refer to similar parts throughout the several views.

On all drawings A, B, and O- are parts of the windstacker of a threshing machine.

A is the upper part of stacker tube passing through a frame of wood, not here shown, which frame of wood is attached to rear of machine holding upper part of stacker and on which it swings.

B is that part of the stacker tube between the fan drum and elbow boxed up with wood to keep the elbow from slipping down. v

C is the elbow, which constitutes parts of a windstacker, and for and upon which I make no claim for patent, nor any of the parts shown in Fig. 5.

My improvements constituting my attachment consist of hinge N; cap E; spring H; lever G; groove P; thumb pin S; hinges M; screw eye O as shown in Fig. 1, and Fig, 4, and so shown as they appear when attached to the elbow of a windstacker.

As before stated, A shown on all figures is a tube entering through a frame of wood, not here shown, which frame of wood is attached to rear of machine, holds upper part of stacker, and on which it swings.

N is a hinge shown on Fig. l, and on Fig. 4, which hinge N is attached to tube A and also to cap E, which capE is shown on Fig. l and Fig. 4; cap E holds elbow O in position; G is alever which is attached to and holds cap E in place; Il is a spring attached to lever G, and

which spring H is attached to a frame on top of the threshing machine; P is a groove made in av'separate piece of metal riveted to elbow C in which groove the lever G rests. The spring H is shown only on Fig. l and Fig. 4; S, shown only on Fig. 4, is a thumb pin holding lever G resting in groove P and holds the spring H in place.

K is an eyelet shown on Fig. l to which spring H is attached; M is a pair of hinges shown in Fig. I and Fig. 4 for breaking or lowering the elbow C, which hinges are attached to elbow C and to B; screw eye O is attached to spring N and also the frame of wood attached to the rear of the machine through which tube A passes.

The following explanation is necessary in order that the usefulness of my invention may be understood. Straw will clog in the elbow part of the windstacker of a threshing machine, and much more frequently when wet, and the method of clearing it of clogged straw from the elbow without my attachment is as follows: Where the elbow is detachable, the machine is first stopped, then loosen thumb screw J shown on Fig. 5, raise a metal band I and pull elbow O of the boxing B shown at awa, and set the elbow C on the ground and clean the clogged straw from the elbow either with a fork or with the hand, and then replace elbow in proper position before starting the machine. Where the elbow is not detachable, the method of clearing the elbow of windstacker is to stop the machine, and then with a long pole clean out the straw, or some crawl in and remove the straw. The clearing of straw in this way involves loss of considerable time.

With my attachment affixed to the elbow of the windstacker, the straw that clogs in the elbow is cleared in a fraction of the time that it now takes by the methods above mentioned, and by my attachment the machine is not stopped, but continues in operation while the straw is cleared out, andthe method with my attachment is as follows: Pull out thumb pin S when spring H will draw up cap E which will then release the elbow C and allow said elbow to drop and thus open the same as is shown on plate L Fig. l, and thus while the machine is in operation the air by reason of the rapidly revolving fan forces out the straw.

I claimti 1. The combination with the hinged sections of a stacker tube, of the cap E, pivoted thereto for holding said sections in alineinent and fastening means for the same substantially as described.

2. In combination with the sections of a stacker tube, part of which are hinged together, a cap E, having a lever G secured thereto, said cap and lever being locked against said sections in the alined position, and being withdrawn therefrom by spring H secured thereto, when released, substantially as described.
